Write a function, maxRadius, to find the index of the planet with the largest radius in the array. The function should: Be named maxR

The following c code has the maxR function as the calculator of planet radius.

Code:

#include<iostream>

#include<string>

using namespace std;

//if is not asked to import a math library, it can be used the following Pi value.

const double PI = 3.14;

class Planet

{

private:

 string planet;

 double r;

public:

   Planet ()

 {

   this->planet = "";

   this->r = 0.0;

 }

 Planet (string name, double r)

 {

   this->planet = name;

   this->r = r;

 }

 string collectName () const

 {

   return this->planet;

 }

 double collectR () const

 {

   return this->r;

 }

 double collectVolume () const

 {

   return 4 * r * r * r * PI / 3;

 }

};

int

maxR (Planet * planets, int s)

{

 double maxR = 0;

 int index_of_max_r = -1;

 for (int index = 0; index < s; index++)

   {

     if (planets[index].collectR () > maxR)

{

  maxR = planets[index].collectR ();

  index_of_max_r = index;

}

   }

 return index_of_max_r;

}

int

main ()

{

 Planet planets[5];

 planets[0] = Planet ("On A Cob Planet", 1234);

 planets[1] = Planet ("Bird World", 4321);

 int idx = maxR (planets, 2);

 cout << planets[idx].collectName () << endl;

 cout << planets[idx].collectR () << endl;

 cout << planets[idx].collectVolume () << endl;

}
